Hey.
I have not seen it mentionned here, have you tried, or even considered regulated dc-current supplies for the heaters?
Should have the sound quality of ac-voltage supplies combined with the lack of noise of the dc-voltage supplies.??

Yes, “be”, the DiyHifiSupply supplies that I linked at the last page are the very same supplies that Tentlabs uses.  I am not sure who supply who but since the DiyHifiSupply in China and Tentlabs  in Denmark I am very sure that Tentlabs supplied by DiyHifiSupply. If the conceptually DC supply will be a valid candidate then the DiyHifiSupply is kind of half ass cheap solution. I do not know how much thy charge but without transformers it shells be me more a shipment of those boards from China. I think to do it right it shall be choked filters and currant stabilized, perhaps multiple sections… BTW, the DiyHifiSupply kits have stupid regulation - above 5V and below 5V. It means that if you use 10Y and 2A3 you need separate supply. Well, for the supply that cost $10 it shell not be a big deal…
